You're onto the whole setup and timing aspect. Cockers are fully adjustable in many ways but that means that there's lots of adjustments to be done.
There's a great setup and timing article at
Moody Paintball Products in the Tech Arctiles section. It was my bible when I got my first couple of cockers.
A hint though. A lot of the adjustments in the later steps are based on what you did in the early steps. So start at #1 and work down. If you need to back track go back and adjust what you need and then redo all the others that come after. A lot of the stuff interacts. Especially the hammer lug and 3way setup points.
Step 1 is setting the back block gap.....
Oh, one aspect that is mentioned but passed over fairly fast is the cocking rod knob setup. when the ram pushes the back block back you should still be able to grab the cocking rod knob and pull it back another 1/16 to 1/8 inch. If you cannot do that then the thing stopping the ram travel is not the ram but the hammer lug smashing into the back of the lug slot in the body. This is not good. The ram travel is what should limit the back block travel, not the cocking rod and hammer lug.
